Multivariate linear regression analysis of FSS score.

	B	SE	Beta	P-value
CAG repeat length	0.054	0.025	0.214	0.034
Age of onset	−0.062	0.020	−0.303	0.003
Poor sleep	1.129	0.488	0.224	0.024
HAMD	0.077	0.028	0.272	0.008

Final model, adjusted R² = 0.401, SE, standard error.

Dependent variables: CAG repeat length, Age of onset, Poor sleep, HAMD, ESS.
